(17)O NMR spectroscopy combined with first-principles calculations was employed to understand the local structure and dynamics of the phosphate ions and protons in the paraelectric phase of the proton conductor CsH2PO4. For the room-temperature structure, the results confirm that one proton (H1) is localized in an asymmetric H-bond (between O1 donor and O2 acceptor oxygen atoms), whereas the H2...

Abstract We propose a space-based interferometer surveying the gravitational wave (GW) sky in milli-Hz to ?-Hz frequency range. By 2040s, band, bracketed between Laser Interferometer Space Antenna (LISA) and pulsar timing arrays, will constitute largest gap coverage of astrophysically relevant GW spectrum. Yet many outstanding questions related astrophysics cosmology are best answered by observ...

The feature extraction of Steady-State Visual Evoked Potential (SSVEP) is developed in a frequency domain regardless of the limitation in hardware architecture. We introduced a spectrum intensity ratio as a simple characterization and separation of SSVEP. However, it is difficult to classify an unseeing state of subjects. In this paper, we propose an adaptive threshold to reject the unseeing st...

The protocol used for intermittent photic stimulation (IPS) may determine the likelihood of evoking a photoparoxysmal response (PPR). One-hundred and thirty-five electroencephalograms (EEGs) presenting PPRs, from 125 patients were studied in order to identify the most effective stimulation frequency to evoke a PPR and the effects of repetition of IPS on the occurrence of a PPR. Two stimulation ...
